Gene Details:

  • Gene ID: Ma06_g11140
  • Gene Symbol: MaMYB3
  • Gene Name: R2R3-MYB transcription factor 3
  • Genome:
  • Species: Musa acuminata

Functional Descriptions:

  • A banana R2R3-MYB transcription factor MaMYB3 is involved in fruit ripening through modulation of starch degradation by repressing starch degradation-related genes and MabHLH6.
  • Identified a MYB transcription factor (TF) termed MaMYB3, as a putative protein binding the promoter of MaGWD1, a member of glucan water dikinase (GWD) family which has been demonstrated as an important enzyme of starch degradation.
  • MaMYB3 was ripening- and ethylene-repressible, and its expression was negatively correlated with starch degradation.
  • The ectopic overexpression of MaMYB3 in tomato down-regulated the expression of starch degradation-related genes, inhibited starch degradation and delayed fruit ripening.
  • We conclude that MaMYB3 negatively impacts starch degradation by directly repressing starch degradation-related genes and MabHLH6, and thereby delays banana fruit ripening.
